zenrabbit, listen up.NASA hears words not yet spoken
NASA has developed a computer program that comes close to reading thoughts not yet spoken, by analyzing nerve commands to the throat.
It says the breakthrough holds promise for astronauts and the handicapped.
"A person using the subvocal system thinks of phrases and talks to himself so quietly it cannot be heard, but the tongue and vocal cords do receive speech signals from the brain," said developer Chuck Jorgensen, of NASA's Ames Research Center, Moffett Field, California.
Jorgensen's team found that sensors under the chin and one each side of the Adam's apple pick up the brain's commands to the speech organs, allowing the subauditory, or "silent speech" to be captured.
[...] "A logical spin-off would be that handicapped persons could use this system for a lot of things," he said, as well as persons wanting to speak by telephone without being overheard.
To reach that goal, the team plans to build a dictionary of English words recognizable by speech recognition software.
The equipment will need improved amplifiers to strengthen the electrical nerve signals, which are now run through noise reduction equipment before they can be analyzed.
"The keys to this system are the sensors, the signal processing and the pattern recognition, and that's where the scientific meat of what we're doing resides." Jorgensen said.
